Limit Touch Switch NL

• Instantaneous operation upon contact with extremely limited hysteresis for high-precision position detection.

• Detects minute displacement or lightweight objects with minimal operating force.

• Built-in LED indicator ensures easy operation monitoring.

• DC models provide versatile functions in combination with the S3D2 Sensor Controller.
